A former ag bike safety lecturer says he was only travelling at five kilometres an hour when his quad bike tipped, leaving him battered, bruised and unable to work for several days.

Col Pring, from Pallamallawa in north-west NSW, has sold motorbikes for a living, raced them, and taught All Terrain Vehicle (ATV) safety at Moree TAFE.

He says last weekend’s accident proves that quad bike crashes can happen at any time to anyone.

“As I’ve turned, I’ve accelerated. There was a big clump of dirt and the back wheel has climbed up that and lifted the quad that. My thumb has hit the throttle because everything is out of whack, and bang – it’s shot me off the side!

“I don’t really think I was careless. I just think it was an accident that happened."

Mr Pring's quad bike is not fitted with a roll bar.

"A roll bar wouldn't have made any difference, because the bike only landed on its side."

He suffered a groin injury, grazing and bruising to the right side of his body, and cuts to his head and leg.

Still limping five days after the accident, Mr Pring admits he should have been wearing a helmet.

"I should have been wearing a helmet, but like 95 per cent of people, I don't wear one.
